Description

Technical Field

[0001] The invention relates to the technical field of agricultural equipment, in particular to a tank-type electrostatic sprayer for agriculture. Background Art

[0002] With the development of modern agricultural technology, the application of automated equipment in agricultural production is becoming more and more extensive. In particular, electrostatic spraying technology is favored because it can significantly improve the adhesion efficiency of pesticides or fertilizers, reduce drug drift, and reduce the impact on the environment. It is especially suitable for greenhouses and other facility agriculture.

[0003] Most of the mobile automatic electrostatic sprayers for agriculture on the market currently usually use electric drive to ensure that the equipment can move freely in the predetermined area and complete precise spraying tasks. However, this type of equipment also faces a series of challenges in practical applications. On the one hand, due to the limited load-bearing weight of this type of equipment, the size of the battery and water tank is limited, and the driving force and the electrostatic spray head both require continuous and stable power support, resulting in a large overall power consumption, which will limit its continuous working time. In particular, when working in a large greenhouse or shed, once the equipment stops due to insufficient power, the staff needs to manually replace the battery or move the equipment to a charging station for charging. This process is not only time-consuming and labor-intensive, but also seriously affects work efficiency. On the other hand, existing electrostatic sprayers for agriculture generally lack effective liquid monitoring and automatic replenishment mechanisms. When the internal liquid volume is lower than a certain threshold, if the new liquid is not replenished in time, it will directly affect the spray effect and work efficiency.

A torsion spring 43 is wound around the rotating axis of the rotating block 42. The two ends of the torsion spring 43 are respectively connected to the rotating block 42 and the fixed frame 3. The contact plate 44 is connected to the right side of the inner wall of the charging station 1, and the contact plate 44 is in contact with the inclined surface 4201 at the right end of the rotating block 42. When the mobile trolley 2 is moving, the left end of the rotating block 42 is stuck in the groove 1201, which can prevent the battery 10 from moving forward and backward, so that the battery 10 can be further Limiting to ensure the normal power supply of the battery 10. When the mobile car 2 returns to the charging station 1, the inclined surface 4201 at the right end of the rotating block 42 will contact the contact plate 44, and the contact plate 44 will squeeze the rotating block 42 to rotate, and the torsion spring 43 will deform to make the left end of the rotating block 42 disengage from the groove 1201, thereby not affecting the replacement of the battery 10. When the mobile car 2 is away from the charging station 1, the inclined surface 4201 at the right end of the rotating block 42 will separate from the contact plate 44, and the torsion spring 43 can return to its original state, thereby driving the rotating block 42 to rotate in the opposite direction and reset, so that the left end of the rotating block 42 is re-stuck in the groove 1201, so as to limit and fix the battery 10 on the mobile car 2.

[0036] like Fig. 9 As shown, it also includes a rain shield 45 and a guide plate 46. The front and rear sides of the charging station 1 are connected with the rain shield 45, the rain shield 45 is located directly above the fixed plate 5 and the electric slide rail 8, and the rain shield 45 is inclined. The front and rear sides of the inner wall of the charging station 1 are connected with two guide plates 46, and the left ends of the guide plates 46 on the front and rear sides are bent and expanded to the side away from each other; when the battery 10 is charged on the charging station 1, the rain shield 45 can block the battery 10 directly above it, and can play a role in shielding rain on rainy days to prevent the battery 10 from contacting with rainwater and being damaged. Under the guiding effect of the guide plate 46, the mobile car 2 can be more easily aligned with the inner wall of the charging station 1, so that the mobile car 2 is convenient to return to the charging station 1.
